A character that likes to play around with machines and usually gets filthy doing so. A side effect of his grunginess is that he often turns out to be MrFixit in some way, shape or form.

These characters usually work with mundane objects like cars or stereos or fuse boxes. If they show up in a fantastic setting, they'll often mistrust technology and favor elbow grease to solve a problem. Their way of speech will also make their spaceships sound like normal motor vehicles.

In other words, this is a mechanic, be he mundane or fantastic, with a lot of similar threads regardless of the type.

See WrenchWench for the DistaffCounterpart to this trope.

Not to be confused with the name of the comic book by Tim Eldred or the Firefox app enabling custom scripting.----!!Examples:

[[AC:{{Anime}} and {{Manga}}]]* Sparky from ''Anime/SpeedRacer''.* Keiichi from ''Manga/AhMyGoddess!''* Yusei from ''Anime/YuGiOh5Ds''. You try making motorcycles from scrap parts. THREE TIMES!* The father and son team in ''Anime/CowboyBebop'' who rebuild the Spaceshuttle Columbia. After the Columbia disaster some fans theory that they rebuilt it from the pieces making them even more awesome mechanics.* Duo from ''Anime/MobileSuitGundamWing'' is the resident tinkerer on the team, working for a salvage organization called The Sweepers. Eventually, he runs his own junkyard with his girlfriend [[spoiler: who eventually becomes his wife...and later his ex-wife]], Hilde. Unlike most examples, Duo rarely gets dirty.

[[AC:ComicBooks]]* "Tank" Tinker, mechanic to pilot Hop Harrigan in Franchise/TheDCU. He also appeared in the Hop Harrigan radio show and movie serial.* Wrench from the Thunderiders in the Franchise/MarvelUniverse.* Slic, Chassis [=McBain=]'s robotic mechanic from ''ComicBook/{{Chassis}}''.* The titular character of ''Grease Monkey''. Also a pun, since the character in question is a gorilla.** The pun is turned into a [[HurricaneOfPuns hurricane of them]] when the gorilla instructs his human buddy to use the word "monkey" as often as possible during a visit from a senior inspector. The human does so. Gorilla demands his toolkit-human hand him a monkey wrench. Gorilla sits down to do paperwork, human says he'd like to join in the monkey business. Gorilla polishes the brightwork, human remarks on how happy he looks when engaging in monkey shine. [[spoiler: it's a setup. The inspector is the politically correct type, and chews the human out for engaging in racial slurs.]]** [[YouFailBiologyForever Interesting also in the fact gorillas aren't monkeys. They're apes.]]* Johnny Storm, the Human Torch from the ComicBook/FantasticFour, is an avid racer and tinkerer on cars. In his [[EstablishingCharacterMoment very first appearance]], he says that flying around as the Torch is the only thing he loves more than cars.

[[AC:{{Film}}]]* [[StarWars Han Solo and Chewbacca]], although not because they like it but because they have no choice if they want to keep the Millennium Falcon running.-->'''Luke:''' [on first seeing the Millenium Falcon] What a piece of junk!-->'''Han Solo:''' She'll make point five past lightspeed. She may not look like much, but she's got it where it counts, kid. I've made a lot of special modifications myself.** From the FanFic ''Soft Wars'':--->'''Mac Logo:''' It may not look like much, but she'll make point five past light speed. I've made some special modifications to her. See. (he points at the side of the ship.)--->'''Fluke Codewriter:''' What?--->'''Mac Logo:''' [[http://en.wikipedia.org/wiki/Racing_stripe#Go-faster_stripes The stripe! It's red. Makes it go faster. Really]]. The Falcon will outrun anything the empire has.** ''Film/StarWarsEpisodeIThePhantomMenace'' has Anakin as one of these. Oddly, he apparently gave up this hobby once he became a Jedi, and especially by the original trilogy.* Andy Micklin and Hutch from ''Series/BlackSheepSquadron''.* ''Film/{{Alien}}'': Parker, the Chief Engineer, and Brett, the Engineering Technician* Ed and his fellow auto mechanics in ''I.Q.''.

[[AC:LiveActionTelevision]]* Scotty and '''every''' engineer in ''Franchise/StarTrek''. Which kind of makes sense, since why else would you pick that job if you didn't like to play with machines?** ''Star Trek'' also has Tom Paris, who isn't an engineer in any shape or form ? except on the holodeck, where he loves to tinker around with antique (read: 20th-century) cars and actually calls his program Grease Monkey.*** Actually, he did rebuild an entire shuttle [[spoiler: with an obsessive girlfriend for an AI]] from scrap.* Rizzo from ''Series/{{Mash}}''.* Cooter Davenport from ''Series/TheDukesOfHazzard''.* Henry from ''{{Series/Eureka}}'' is the (only) resident grease monkey. He's actually a literal rocket scientist; he just fixes cars for fun. * Kurt from ''Series/{{Glee}}'' is implied to be a Grease Monkey despite his CampGay tendencies. He's the son of a mechanic and apparently has his own coveralls at the shop. One CrowningMomentOfHeartwarming ended with him going to change out of his ridiculously expensive sweater for some father-son car fixin'.* Damon from ''Series/PowerRangersLostGalaxy''* Kaylee from ''{{Series/Firefly}}'' has strong elements of this. Simon even told her she's pretty, even when, no, ''especially'' when she's covered in engine grease.* In ''Series/{{Supernatural}}'', Dean can take on this role when his baby, the Impala, needs him.

[[AC:{{Radio}}]]* Ichabod "Ikky" Mudd from the ''Captain Midnight'' radio show and its spinoff comics, comic strip and TV show. The TV show later changed its name to ''Jet Jackson, Flying Commando''.

[[AC:VideoGames]]* Any character named "Cid" in a ''Franchise/FinalFantasy'' game will be a technical wizard of some sort, but the one from ''VideoGame/FinalFantasyIV'' fits this trope the best. The dude even fights [[ImprobableWeaponUser with a wrench]] in battle. * Dwarf Engineers from ''VideoGame/WarhammerOnline''. Complete with wrench to beat people with.* [[VideoGame/NintendoWars Andy]] carries around a giant wrench, [[http://images4.wikia.nocookie.net/__cb20080617193741/advancewars/images/thumb/6/62/Orange_Star_CO_Andy.jpg/200px-Orange_Star_CO_Andy.jpg dresses like this]], his CO power is fixing things, and he has lines like "I haven't even cranked the engine yet!"* Scooter in ''VideoGame/{{Borderlands}}'' has the stereotypical accent and manners of a redneck but when it comes to vehicles and machines he's a savant, to the point where he could be considered a MrFixit. This is due to him being a member of the Hodunk clan, who are all rednecks with a talent for mechanics.

[[AC:WesternAnimation]]* Wildcat from ''WesternAnimation/TaleSpin''* Clutch from ''Franchise/GIJoe''.* Monkey from ''ComicStrip/{{Garfield}} in Paradise''.* Coop from ''WesternAnimation/MegasXLR''.
